CB125s Ignition wiring question

[jordan_carson]

As far as I thought i was ready to set the points gap and timing then try and kick over my cb12s project. Of course there would be another issue right before hearing it run.

I believed I had a strong understanding of the ignition wiring as I had been succesful wiring two cb350's before this bike but alas theres something else I need to learn.

Attached is a basic diagram of how I have the bike wired.

The issue I am having is that even when I separate the contact breakers very far apart I am showing a charge through the contact breaker spring arm ( which I thought will only show a charge when the contact breakers are less than the 0.3-0.4mm gap apart)

There was a mild amount of corrosion on the base plate as well as the points themselves so I cleaned them as best I could and tried again but still experienced the same issue.

I tested my coil with a multimeter and monitored 3.5-4.5 ohms which is within the allowable limit

I attempted testing my condenser however did not see readings that made sense.

Any advice would be greatly appreciated. I am now contemplating purchasing new points, mechanical advancer, coil and condenser but wanted to check here to see if I royally screwed something up.

Might be the insulators on the points spring. I had a similar issue with an SL350 I used to own. New points fixed it.

Alright now after installing my new clean points I am having new problems.

Is the coil uni directional? When I have power coming in through the black wire and coming out of the blue wire into the condensor/points I am blowing fuses as soon as i flip the power switch.

If I disconnect the fuse and the coils and test the circuit up to that point by plugging in a light where the coil was the fuse doesnt blow and I get power to the light.

I have sanded the grounds beneath the coil mount really well and sanded the ground I have the condensor going to. I currently dont have any other electrical component then what is pictured above.

Also I dont think this is an issue but the to create a parallel flow coming out of the coil i simply split a 8'' wire and connected the blue wire from the coil to this split. I then took the two free ends of the 8'' wire and attached them to their respective points/condensor.

The points are grounded simply by being screwed in against the base plate correct?
